`core-splitter` provides a split bar and dragging on the split bar
will resize the sibling element.  Use its `direction` property to indicate
which sibling element to be resized and the orientation.  Usually you would want
to use `core-splitter` along with flex layout so that the other sibling
element can be _flexible_.

Example:

    <div horizontal layout>
      <div>left</div>
      <core-splitter direction="left"></core-splitter>
      <div flex>right</div>
    </div>

In the above example, dragging the splitter will resize the _left_ element.  And
since the parent container is a flexbox and the _right_ element has
`flex`, the _right_ element will be auto-resized.

For horizontal splitter set `direction` to `up` or `down`.

Example:

    <div vertical layout>
      <div>top</div>
      <core-splitter direction="up"></core-splitter>
      <div flex>bottom</div>
    </div>
